Subject: Re: [edk2-devel] [Patch v2 03/11] BaseTools GenFw: Fix the issue to update the wrong size as SectionSize
Date: Wed, 16 Oct 2019 09:27:17 +0000	[thread overview]
Message-ID: <08650203BA1BD64D8AD9B6D5D74A85D16154B171@SHSMSX104.ccr.corp.intel.com> (raw)
In-Reply-To: <1571099210-12432-4-git-send-email-liming.gao@intel.com>

Hi Liming,

Would you please add more description in commit message? This patch is in the patch set of CLANG9 enabling, but it's hard for me to see the direct relationship between CLANG9 and this fix and why the original code is wrong.

Thanks
Bob
